      Fixed bug #36632: SELECT DISTINCT from a simple view on an · fc827ae3
      Gleb Shchepa authored
                        InnoDB table, where all selected columns
                        belong to the same unique index key, returns
                        incorrect results
      
      Server executes some queries via QUICK_GROUP_MIN_MAX_SELECT
      (MIN/MAX optimization for queries with GROUP BY or DISTINCT
      clause) and that optimization implies loose index scan, so all
      grouping is done by the QUICK_GROUP_MIN_MAX_SELECT::get_next
      method.
      
      The server does not set the precomputed_group_by flag for some
      QUICK_GROUP_MIN_MAX_SELECT queries and duplicates grouping by
      call to the end_send_group function.
      
      Fix: when the test_if_skip_sort_order function selects loose 
      index scan as a best way to satisfy an ORDER BY/GROUP BY type
      of query, the precomputed_group_by flag has been set to use 
      end_send/end_write functions instead of end_send_group/
      end_write_group functions.

      backport from 6.0 · 790edf00
      Gleb Shchepa authored
            
      Bug#35658 (An empty binary value leads to mysqld crash)
              
      Before this fix, the following token
        b''
      caused the parser to crash when reading the binary value from the empty string.
      The crash was caused by:
        ptr+= max_length - 1;
      because max_length is unsigned and was 0, causing an overflow.
              
      With this fix, an empty binary literal b'' is parsed as a binary value 0,
      in Item_bin_string.

      Bug#37003 Tests sporadically crashes with embedded server · 30bd1d7c
      Davi Arnaut authored
      The problem was that when a embedded linked version of mysqltest
      crashed there was no way to obtain a stack trace if no core file
      is available. Another problem is that the embedded version of
      libmysql was not behaving (crash) the same as the non-embedded with
      respect to sending commands to a explicitly closed connection.
      
      The solution is to generate a mysqltest's stack trace on crash
      and to enable "reconnect" if the connection handle was explicitly
      closed so the behavior matches the non-embedded one.

      Bug #37024: Wrong location of messagefiles · aa45d0c0
      Timothy Smith authored
      make_binary_distribution.sh got clobbered by the 5.0 version during a merge.
      This caused a few packaging problems, including message files put in the wrong
      place and some missing files.  Fix is just to revert back to the 5.1 version
      from before the merge.
      
      Problem introduced in
      ChangeSet 1.2606.2.1 2008/05/13 15:56:07 kent@kent-amd64.(none)
      
      This change was made in the 5.1.25 release clone in BK, but never made it to the main mysql-5.1 BK tree.  I am adding it to mysql-5.1 bzr.
